Abstract
A substrate surface may be modified with a polymer coating to render the surface suitable for plasma functionalization. The polymer coating is deposited onto the surface at ambient temperature to a thickness of less than 0.1 μm. The polymer coating includes poly(p-xylylene) or a derivative thereof, and is capable of penetrating into pores of a porous substrate while no substantially altering the porosity of the substrate. The coated substrate is selected from a material lacking a primary or secondary aliphatic hydrogen atom.
